A 64-year-old woman had a right-sided breast mass that had been present for 25 years. She noted a purulent, malodorous discharge. On physical examination, she had a 40-cm mass involving the entire right chest wall (Figure 1 and Figure 2). The mass was not fixed to the underlying chest wall. She had no adenopathy. There was a purulent exudate on the surface and several necrotic abscess cavities. An incisional bi-opsy was performed in the office, and she was admitted to the hospital. A chest x-ray film and a thoracic computed tomographic scan were normal, excluding the fungating mass on the chest wall. The patient died in the hospital 4 days after her admission.
